The power delivered by the propeller is, amongst others, a function of blade area. If the blades must be wider (to accomodate anti-icing features) then they need to be made shorter or their number must be reduced, otherwise they do not match the power delivered by the engine.

If these pusher props are made shorter they become less efficient because part of them is already obstructed by the engine and the wing, so instead they decreased the number of blades.

I could be wrong, in which case I would like to know what the real reason is ;)

Can you explain why 3 blades are better than 6 in cold weather? Thanks.
